RESERVOIR-BRUSH.

SPECIFICATION forming part of Letters Patent No. 403,566, dated May 21,1889.

Application filed August 30,1888. Serial No. 284,169. (No model.)Patented in England February 28, 1888. No. 811, and in France July 30,1888, No.1'79,070.

f aZZ whom it may concern.-

Be it known that I, WALTER II. UNDER- WOOD, a citizen of the UnitedStates, residing at Yonkers, \Vestchestcr county, State of New York,have invented a new and useful Improvement in Reservoir-Brushes, ofwhich the following is a full, clear, and exact specification.

In Letters Patent Nos. 37 8,7 42, 37 8,7 123, and 378,714, heretoforegranted to me, I have described a nozzle for distributing; fluids,consisting of a hollow flexible nipple of conical, tapering, or otherform, adapted to be applied to a reservoir and slit in such manner thatthe sides or lips of the slit normally close to gether and seal thereservoir, but will open on the application of pressure bending ordeflecting the nozzle, thereby permitting the escape of the fluid, whichis spread over the surface against which the end of the nipple ispressed by the trowel-like action of such end.

M y invention, for which English Patent No. 2511 was granted under dateof February 28, 1888, and for which application for Letters Patent inFrance, No. 179,070, under date of July 30, 1888, has been made, andwhich is hereinafter fully set forth, is an improvement onfluid-distributors of the above-described character, and is illustratedin the accompa nying drawings, in which Figure 1 is a perspective viewillustrating one form of nozzle embodying my invention. Fig. 2 is across-section of the nozzle shown in Fig. 1. Fig. 3 is a sectional viewshowing the nozzle applied to a bottle and in the position to distributeand spread the liquid. Fig. l is a sectional view of part of a bottleand nozzle, illustrating a modification. Fig. 5 is a perspective viewshowing one feature of my improvement as applied to a nozzle of adifferent shape.

The nozzle is'of any suitable form adapted for application to or tooperate with a reservoir to which the nozzle is applied and secureddetachably or otherwise. As illustrated, the nozzles are of the formsused when they are made of india-rubber or other flexible and preferablyelastic material, each nozzle terminating in a flat-faced blade ortrowel,

a, and having a beaded rim, 1), which may be expanded over the neck ofthe bottle X or other receptacle and will contract on and adhere to thelatter.

The blade, as shown in Figs. 1 to at, has two converging faces, andextends centrally from the flat end 0 of the nozzle, and at each side ofsaid blade the end is slit at an angle to the face, the two slits c cconverging inward, as shown in Figs. 2 and 3, or outward, as shown inFig. 4.

The slits are formed by cutting the material without removing anyportion, so that the lips close normally together by the clasticity ofthe material and seal the reservoir and protect its contents from theinfluence of the external air.

The blade a is preferably solid or otherwise rendered less flexible thanthe body of the nozzle, so that when the reservoir is inverted and theblade is applied to the surface to be coated sufficient pressure willforce the blade either laterally, as shown in Fig. 3, or the end 0 willbe carried down away from the base of the blade, as shown in Fig. 4. Ineither case the lip of the slit or orifice formed by the blade or partannexed directly thereto will be separated from the opposite lip, whichis directly on the body of the nozzle, and an orifice will be presentedfor the passage of the liquid.

In order to facilitate the flow of the liquid from the reservoir, Iprefer to make additional slits in the body ofthe nozzle, so situatedthat one of such slits will be opened by the bending or strain of thebody when the lower orifice is opened for the passage of the liquid.Thus there is a supplemental slit, 1', beyond each slit cin position tobe above the same when the reservoir is inverted, and the straining ofthe nozzle from pressing the blade at against the surface to be coatedopens also the slit i sufficiently to admit air if there is any tendencyto a vacuum within the receptacle.

Without limiting myself to the precise construction and arrangement ofparts shown, I claim- 1.. A nozzle provided with a flattened slit end offlexible material and with a terminal blade of greater rigidityprojecting outward adjacent to the slit, substantially as described.

2. The within-described nozzle, having a body portion adapted forattachment to a reservoir and closed by a top, a, a solid bladeextending from said top, and slits e e, at an angle to each other in thetop at the base of the blade, substantially as described.

3. A nozzle composed of a hollow nipple of flexible material havingdistributing-slits e,

and air-inlet slits 2', substantially as and for 10 the purpose setforth.

Intestimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
